NGC 7023 Iris Nebula

NGC 7023 Iris Nebula

I tried the Iris Nebula a few weeks ago from my home. Just 20 minutes (13 x 90s) at 280mm without guiding. But that’s not camparable with this one…

I was very careful with the polar alignment and balance. And I had luck. I did a test shot with 180 seconds (this time I’ve from a calculation chart that I found in the net… it’s based on the declination value of the object, focal length and some other things) and was very pleased with the result 🙂

On 2-3 subs I had a very small dec-drift. But all in all I’m very impressed about the capabilities of the MGEN and the Star Adventurer. Also the Dithering is great! Almost no background noise structures anymore 🙂

Unfortunately I noticed very late the dew on the lens during the session…
More than one hour was worthless…
